CROSS-REFERENCE TO RELATED PATENT APPLICATION

This patent application is a continuation of U.S. patent application Ser. No. 16/719,629, filed Dec. 18, 2019, which claims the benefit of U.S. Provisional Patent Application No. 62/782,155, filed Dec. 19, 2018, the entire teachings and disclosure of which are incorporated herein by reference thereto.

FIELD OF THE INVENTION

This invention generally relates to multi-port valves, and more particularly to multi-port valves having multiple inlet and outlet ports to control flow in different planes.

BACKGROUND OF THE INVENTION

Multi-port valves are used in a variety of industries and applications. Such valves include one or more inlet ports and one or more outlet ports. A valve member disposed within a housing of the valve is responsible for governing the flow between the various ports. A portion of the valve member, e.g. a valve stem, protrudes from the housing and is acted upon by an actuator attached to the multi-port valve. As result, the actuator governs the position of the valve member within the housing, which in turn governs the flow between the various ports.

Such multi-port valves advantageously provide a single flow device which can effectively replace multiple flow devices which only employ a single inlet and a single outlet. However, such multi-port valves are not without their own drawbacks. For example, the overall complexity of the valve increases as the number of ports increases. This can lead to relatively high part count assemblies. Further, this complexity in construction also results in a more complex manufacturing process for making the valve. Indeed, the multiple ports are associated with multiple inlets and outlets of the valve which must be welded onto a housing. Further the desired fitting for each inlet and outlet must also be welded on to its respective inlet or outlet.

Such welded up assemblies increase the number of potential leak paths of the valve. Further, to achieve such welds, special machining steps are often needed at the inlets and outlets as well as the housing to ensure there is a tight fit between these components for subsequent welding.

Furthermore, a number of individual seals are required to effectively seal the various ports of the multi-port valve off from one another. These multiple seals also lead to an increase in overall cost and complexity of the multi-port valve.

Multi-port valves that overcome these issues are available from the assignee of the instant application, and are described in U.S. Pat. No. 9,212,751 (“Valve system and method” by Allan R. McLane et al.), issued Dec. 15, 2015, and co-pending U.S. patent application Ser. No. 15/945,173 (Publication No. 2018/0292016, “Multi-port valve” by Joe Ledvora et al.), filed Apr. 4, 2018, and claiming priority to U.S. Provisional Application No. 62/483,167, filed Apr. 7, 2017, the teachings and disclosure of which are hereby incorporated in their entireties by reference thereto.

In many applications that utilize such multi-port valves, fluid flow in multiple planes is required and typically provided via the external plumbing in the fluid control system. Unfortunately, the use of such external plumbing greatly increases the required volume or footprint of the overall fluid control system, and can create problems necessitating re-routing and re-locating of other components in its or other systems that need to occupy that volume.

Accordingly, there is a need in the art for a multi-port valve that provides multi-planar fluid flow and control within the volume of the valve itself. Embodiments of the present invention provide such a multi-port multi-plane valve. These and other advantages of the invention, as well as additional inventive features, will be apparent from the description of the invention provided herein.

BRIEF SUMMARY OF THE INVENTION

In one aspect, embodiments of the present invention provide a multi-port multi-plane valve having a reduced part count and a reduced cost relative to prior designs, and that provides multi-planar fluid flow and control. An embodiment of such a multi-port multi-plane valve includes a housing. The housing defines an internal cavity. The housing further includes a plurality of ports, at least one of which lies in a different plane from the other(s). Preferably, at least one of the ports lies in a plan normal to the plane of the other ports. Each of the plurality of ports is in communication with the internal cavity.

A preferred embodiment also includes a shell body rotatably disposed within the internal cavity. This shell body is configured to provide flow between different ports existing in the same plane and between different ports existing in different planes based on its angular position within the valve housing.

A seal member is also provided which has a plurality of openings and surrounds the shell body such that it circumscribes the shell body within the internal cavity. In certain embodiments, each opening of the plurality of openings of the seal member is associated with one of the plurality of ports lying in one plane such that each of the plurality of ports in that plane are sealed from one another along the outer periphery of the seal member.

In certain embodiments, the seal member seals outwardly in a radial direction against an interior surface of the housing. In other embodiments, the seal member includes a plurality of seal ribs which seal against the shell body. The seal member may be one of a continuous piece of elastomeric material, or comprises a rigid core with a plurality of elastomeric seals attached thereto.

In certain embodiments, the valve also includes a plurality of port bodies, respectively received in the plurality of ports such that one port body of the plurality of port bodies is received in one port of the plurality of ports. In certain embodiments, the seal member comprises a plurality of seal segments.

Other aspects, objectives and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Turning now to the figures, as will be understood from the following, embodiments of a multi-port multi-plane valve assembly and its associated multi-port multi-plane valve are described herein. The multi-port multi-plane valve advantageously overcomes existing problems in the art by presenting an overall construction with a reduced part count, a reduced number of potential leak paths, a reduction in overall assembly time and cost, and reduced external plumbing to provide fluid flow and control in multiple planes.

As discussed in the above identified co-pending U.S. patent application Ser. No. 15/945,173 (Publication No. 2018/0292016, “Multi-port valve” by Joe Ledvora et al.), filed Apr. 4, 2018, the teachings and disclosure of which is hereby incorporated in its entirety by reference thereto, multi-port valve assemblies typically, as here, include an actuator (not shown herein) mounted to the multi-port valve. The actuator is responsible for actuating a valve member (i.e., a shell body as described below) which in turn governs the flow characteristics through the valve. The actuator may be any style of actuator typically used in valve actuation, e.g., rotary, linear, etc., and may rely on any type of power source typically used in valve actuation, e.g., electric, hydraulic, and pneumatic, etc. Monitoring of the rotational position of the valving member may also utilize any type of position sensing, e.g., via a Hall-effect sensor, potentiometer, stepper motor control, etc. As such, the actuator and position sensing are non-limiting on the invention herein.

Turning now to FIG. 1 , an embodiment of the multi-port multi-plane valve 32. Valve 32 includes a housing 40. In one advantageous implementation of the invention, housing 40 is formed as a single piece. By “formed as a single piece” it is meant that the main body of housing 40 and its associated ports are not an assembly of separate components which are subsequently joined together by a joining process, e.g., welding, as is done in conventional valve housings. Rather, housing 40 is formed as a single unitary piece by any process capable of achieving such a configuration, e.g. injection molding, 3D printing, etc. However, it is contemplated by the teachings herein that housing 40 may be embodied as an assembly of separate components which are subsequently joined together by a joining process.

As illustrated, housing 40 includes a plurality of ports, in particular, a first port 42, a second port 44, a third port 46, a fourth port 48, and a fifth port 50 (see FIG. 7 ) that lies in a plane or along an axis that is normal to the plane of the other four ports 42, 44, 46, 48 in the illustrated embodiment. Of course those skilled in the art will recognize that other angles may be provided. Each of the ports 42, 44, 46, 48, 50 are in fluid communication with an internal cavity 56 of housing 40. Further, each of ports 42, 44, 46, 48, 50 may function as an inlet or an outlet, or both, of valve 32.

Still referring to FIG. 1 , internal cavity 56 receives a generally cylindrical shell body 58 which operates as a valve member for controlling the flows between the plurality of ports 42, 44, 46, 48, 50. A seal member 60 is also received in cavity 56 and surrounds the outer periphery of shell body 58. This seal member 58 is a continuous cylindrical element, except for the openings formed therein. As will be discussed below, seal member 60 is a single piece seal which advantageously creates a seal for each of the plurality of ports 42, 44, 46, 48 to prevent unintended cross flow or short circuiting.

Seal member 60 also advantageously entirely seals internal cavity 56, such that no additional seals need be associated with port 50 or a cover 62 (see FIG. 7 ) of valve 32. It is possible, however, that seal member 60 may also be formed as separate seal segments which immediately next to one another in the circumferential direction, which together define a seal member which surrounds the shell body 58. The term “seal member” as used herein includes both configurations, i.e. a single unitary seal member, or a seal member formed of a plurality seal segments.

Shell body 58 includes a plurality of openings. The openings of seal member 60 remain statically aligned with ports 42, 44, 46, 48, 50 so that each opening is associated with one port, and seals against an interior surface of housing 40 that defines cavity 56, around the opening of the port into cavity 56. Opening 20 and 22 in shell body 58, however, are selectively alignable with ports 42, 44, 46, 48, and opening 24 is aligned with port 50 to govern the flows between the ports. The shell body 58 includes a valve stem 64 (see FIG. 7 ) which extends through an opening in housing 40. This valve stem, and in turn the remainder of shell body 58, is rotatable about axis by an actuator as discussed above.

A plurality of port bodies, namely, a first port body 224, a second port body 226, a third port body 228, a fourth port body 230, and a fifth port body 232 (see FIG. 7 ) are respectively received in the first through fifth ports 42, 44, 46, 48, 50 as illustrated. The port bodies 224, 226, 228, 230 are substantially identical to one another, but port body 232 differs in the illustrated embodiment. Port body 224, 226, 228, 230 includes a through bore 238, 240, 242, 244 which communicates with an internal cavity 56 containing shell body 58 rotatably disposed therein through port 42, 44, 46, 48, respectively, of housing 40. Port body 232 provides passage through port 50 of housing 40 as shown in FIG. 7 .

Having now described the structure of an embodiment of the present invention, attention will now be directed to the orientation of the shell body 58 in each of FIGS. 1-6 to discuss the fluid control provided by rotation thereof.

As shown in FIG. 1 , the shell body 58 is located in a first position referred to herein as 0°. In such position the openings 20 and 24 provide fluid communication between ports 48 and 50 (see FIG. 7 ) and provide a change in the axis of flow between the two different planes in which the ports 48 and 50 lie. In this position the opening 22 provides fluid communication between ports 42, 44, and 46. This communication is equal between ports 42 and 44, and may provide a 50%-50% mix of fluid flow from ports 42, 44 into port 46, or vice versa, in certain implementations. Indeed, the percentage mix or flow can be varied between the ports 42, 44 by rotating the shell body 58 to provide a greater or lesser communication with opening 22.

Once the shell body 58 has rotated about 24° in the illustrated embodiment as shown in FIG. 2 , port 44 is isolated such that it has no fluid communication to any of the other ports. However, fluid communication is still provided between ports 42 and 46 (and between 48 and 50). A rotation of the shell body 58 about 24° from the orientation of FIG. 1 in the other direction as shown in FIG. 3 isolates port 42 such that it has no fluid communication to any of the other ports. However, fluid communication is still provided between ports 44 and 46 (and between 48 and 50). As the angle of rotation is varied, the area of the openings 20 and 22 that is exposed to the particular port also varies once an edge of the opening moves past the seal 60 edge.

FIGS. 4-6 illustrate similar rotational alignments as shown in FIGS. 1-3 , but starting with an orientation of the shell body 58 that is 180° from that shown in FIG. 1 . Such orientations provide fluid communication between ports 46 and 50, and variable mixing (or division) of flow between ports 42, 44, and 48, as well as isolation of ports 42 and 44 as discussed with regard to FIGS. 2 and 3 .

With the symmetrical layout of the four ports 42, 44, 46, 48 and the openings 20, 22, similar operation will become apparent to those skilled in the art from the foregoing when the shell body 58 is initially oriented at 90° and 270° from the orientation shown in FIG. 1 , and a discussion thereof will be forgone in the interest of brevity.

FIGS. 7, 8 provide isometric side views of the embodiment of the multi-port multi-plane valve 32 shown with the shell body 58 positioned as shown in FIG. 1 when viewed into port body 224 and 228, respectively. FIG. 9 provides isometric side views of the embodiment of the multi-port multi-plane valve 32 shown with the shell body 58 positioned as shown in FIG. 2 when viewed into port body 228.

Turning now to FIGS. 10 and 11 , there are illustrated isometric views of an embodiment of a multi-port multi-plane valve similar to that discussed hereinabove. However, the reference numerals have been removed and replaced with five port designations 1-5 to simplify the understanding of the operation thereof for the following description. In order to aid in this description, the isometric cross-sectional view of FIG. 12 is also instructive as it illustrates the internal passages and the shell body with the same five port designations 1-5. Further, FIG. 12 and the figures included thereafter introduce flow arrows and blocked flow symbols to aid in the understanding of the operation of the valve. However, it should be noted that the directional heads of the flow arrows shown in FIGS. 12-20 are not limiting on the flow direction through the valve, but instead only illustrate possible flows through the valve based on the communication enabled by the positioning of the shell body. Indeed, flow in other directions is also possible based on the external plumbing and flow system, and flow in both directions at different times through the same ports based on these external factors is also possible.

Turning now to FIG. 13 , the shell body is located in a first position referred to herein as 0°. In such position the shell body provides fluid communication between ports 3 and 5, and fluid communication between ports 1, 2, and 4. As the shell body is rotated, the percentage flow can be varied between the ports 2 and 4 to provide a greater or lesser flow from port 1.

Once the shell body has rotated about 24° in the illustrated embodiment as shown in FIG. 14 , port 4 is isolated as shown by the blocked flow symbol such that it has no fluid communication to any of the other ports. However, fluid communication is still provided between ports 1 and 2 (and between 3 and 5). A rotation of the shell body about 24° from the orientation of FIG. 13 in the other direction as shown in FIG. 15 isolates port 2 as shown by the blocked flow symbol such that it has no fluid communication to any of the other ports. However, fluid communication is still provided between ports 1 and 4 (and between 3 and 5).

FIGS. 16-18 illustrate similar rotational alignments as shown in FIGS. 13-15 , but starting with an orientation of the shell body that is 180° from that shown in FIG. 13 . Such orientations provide fluid communication between ports 1 and 5, and variable flow between ports 3, 2, and 4, as well as isolation of ports 4 and 2 as discussed with regard to FIGS. 14 and 15 .

With the symmetrical layout of the four ports 1-4 and the openings in the shell body, similar operation will become apparent to those skilled in the art from the foregoing when the shell body is initially oriented at 90° and 270° from the orientation shown in FIG. 13 , and a discussion thereof will be forgone in the interest of brevity.

With reference now to FIGS. 19 and 20 , there is illustrated an embodiment of the multi-port, multi-plane valve that includes a shell body having a first and a second flow enhancer channel 20A, 20B provided on either side of the opening 20. These flow enhancer channels 20A, 20B also provide fluid communication to opening 24 leading to port 5, and operate to increase the flow thru the right angle opening when the shell body has been rotated to a position that is blocking the flow through one of the ports (4 in FIGS. 19 and 2 in FIG. 20 ) on the other side of the valve. Such enhanced flow reduces the pressure drop occurring on one side of the valve when controlling flow paths on the other side of the valve. In embodiments, opening 20 is wider than the first flow enhancer channel 20A and wider than the second flow enhancer channel 20B. Further, in embodiments, the first flow enhancer channel 20A has the same width as the second flow enhancer channel 20B.

As described herein, embodiments of the present invention The multi-port multi-plane valve advantageously overcomes existing problems in the art by presenting an overall construction with a reduced part count, a reduced number of potential leak paths, and a reduction in overall assembly time and cost. In embodiments, the multi-port multi-plane valve has particular suitability for routing coolant in a thermal system, e.g., an engine or motor of a vehicle. For example, the multi-port multi-plane valve can be used to route coolant in a first thermal loop and at least one other thermal loop. In embodiments, a first thermal loop may be to route the coolant to engine/motor components or a battery in need of cooling or warming, and a second thermal loop may be provided to cool or warm the coolant (e.g., to a radiator, chiller, or heater). Depending on the particular needs of the coolant and the components to which it is being routed, the shell body 58 is able to be rotated to direct the flow of coolant through the desired thermal loops.
